“…Oliveira et al (1996Oliveira et al ( , 1998Oliveira et al ( , 2004 and Jordan and Ince (1986) have shown that harvest of primocane-fruiting raspberry can easily be delayed in production systems that include summer pruning of primocanes, tipping, and tunnel protection. With the use of greenhouses, scheduling primocane-fruiting raspberry for year-round production is possible (Dale et al, 2001(Dale et al, , 2005 and often includes the combination of floricane-and primocane-fruiting cultivars (Dijkstra and Scholtens, 1993;Faby, 1993;Hamminga, 1995;Oliveira et al, 2004). Scheduling floricane-fruiting blackberry for year-round production has been reported using artificial chilling and forcing in greenhouses (Bal and Meesters, 1995).…”

Primocane-fruiting blackberries (Rubus subgenus Rubus Watson) may offer opportunities for season extension and off-season fruit production, particularly in mild climates with protected culture. In May 2005, plants of ‘Prime-Jan’® were established at the Oregon State University–North Willamette Research and Extension Center, Aurora, OR. Half of the planting was established under a high tunnel and the remainder planted in an adjacent open field. In 2006 to 2007, primocanes were subjected to four treatments to promote branching and/or delay harvest: 1) all primocanes within the plot were cut to the ground when averaging 0.25 m tall, then later emerging canes soft-tipped when reaching 0.5 m tall (C0.25m/T0.5m); 2) all primocanes within the plot were cut to the ground when averaging 0.5 m tall, then later emerging canes soft-tipped when reaching 0.5 m (C0.5m/T0.5m); 3) primocanes double-tipped: all primocanes within the plot were soft-tipped when averaging 0.5 m tall with subsequent lateral branches then soft-tipped when reaching 0.5 m long (T0.5m/Tb0.5m); and 4) primocanes were soft-tipped when averaging 0.5 m tall (T0.5m; control). The tunnel was covered with plastic from 5 Sept. 2006 and 31 Aug. 2007, ≈1 to 2 weeks before harvest until the end of harvest to protect fruit from inclement weather. On average, fruit harvest began on 12 Sept. in the open field and tunnel, but lasted ≈3 weeks longer in the tunnel, ending on 16 Nov., on average. Primocanes that were double-tipped had nearly twice the flowers and fruit than canes that were soft-tipped only once (T0.5m; control). In the tunnel, cumulative yield of double-tipped primocanes averaged 10.7 t·ha−1 in 2006 and 19.3 t·ha−1 in 2007, a 267% and 159% increase compared with the control, respectively. On average, cumulative yield for all treatments was less in the open field than in the tunnel, although cultural systems could not be compared statistically. Harvest was not delayed in the C0.25m/T0.5m treatment in 2006 compared with the control and the double-tipped treatments; however, in 2007, harvest was delayed by 2 weeks in C0.25m/T0.5m. In contrast, harvest was delayed by ≈4 weeks when primocanes were cut to the ground at 0.5 m (C0.5m/T0.5m). Primocanes that were double-tipped produced heavier fruit than other treatments (33% heavier than the control, on average). Double-tipped primocanes did not have more ovules per flower, but had significantly more drupelets set compared with the control. In addition, plants growing under the tunnel tended to produce heavier fruit (32%, on average) than those grown in the open field. Harvest date affected fruit pH in 2006, but not in 2007. In 2006, fruit pH was highest in the early season. All other differences in fruit chemistry were not significant. The pruning and tipping systems used here increased yield and offered options for season extension.

“…Each production technique must be adapted to a particular region. In northern Europe, researchers developed various technologies using cold-treated canes of summer-fruiting cultivars grown in pots in heated greenhouses (Dijkstra and Scholtens, 1993;Faby, 1993;Lantin et al 1971;Meesters and Pitsioudis, 1993). Although expensive, these techniques have been profitable due to the high off-season prices.…”

The spring shoots of `Autumn Bliss' red raspberry (Rubus idaeus L. var. idaeus; primocane-fruiting type) were cut on 2, 16, 31 July and 15 and 30 Aug. with the objective of delaying fruit harvest into the off-season under mild winter climatic conditions. Cutting shoots in August delayed fruit harvest until February and April of the following year, but shoot growth was weak and fruit yield low (4.8 and 2.1 g/cane). July cuttings delayed harvest until October to January with acceptable fruit yield (63.5, 52.8, and 26.5 g/cane for 2, 16, and 31 July, respectively). The differences in cane height and total node and fruiting node count between the three cutting dates of July were small, but there was a constant decrease in leaf area per cane from the first to the third date and a sharp decrease in fruit yield from the second to the third date. Vegetative shoot growth was less affected than yield when summer cutting was delayed until the end of July to induce a later harvest. Fruit quality always reached acceptable standards. This study confirms the practicability of using summer-cutting of primocane-fruiting red raspberries to induce off-season fruit production under protected cultivation in mild winter climates.

“…Para forzar la cosecha de fruto en campo o en invernadero a la época de mejor precio que transcurre de septiembre a abril (Muñoz y Juárez, 1997;Guzmán-Soria et al, 2004), es posible realizar diversas prácticas culturales como aplicación de promotores de brotación (aceite mineral emulsificado, cianamida de hidrógeno, ácido giberélico) (Rodríguez y Almaguer, 1980;Snir, 1986Snir, , 1988, suministro de frío de manera natural o artificial (Dijkstra y Scholtens, 1993;Faby, 1993;Pritts et al, 1999;Dale et al, 2003) y podas en diversas épocas e intensidades (Oliveira et al, 1996(Oliveira et al, y 2004.

“…La producción de frambuesa en condiciones de invernadero o túnel de polietileno inició hace más de diez años (Dijkstra y Scholtens, 1993;Faby, 1993) y en comparación con el sistema de producción en campo, tiene ventajas en la programación de la cosecha y la formación de frutos más grandes, firmes y menos propensos a pudrición, aunque sean ligeramente menos dulces y más ácidos, pero aún dentro de los estándares de calidad del mercado (Pritts et al, 1999). En condiciones protegidas, la frambuesa se ha explotado con o sin suministro de frío de manera natural o artificial, tanto en variedades productoras de verano (productoras en tallos del año anterior) como en productoras de otoño (Dijkstra y Scholtens, 1993;Pritts et al, 1999;Dale et al, 2003); éstas últimas ofrecen ventajas al producir dos cosechas anuales, utilizar menos plantas por unidad de superficie y de esta manera reducir costos de producción (Dale et al, 2003).…”

En regiones con clima templado, el cultivo en campo de la frambuesa (Rubus idaeus L.) ‘productora en tallos del año’ (productora de otoño) se hace mediante dos sistemas de manejo para obtener una o dos cosechas anuales. En esta investigación se evaluaron dos sistemas de manejo modificados, a los cuales se les agregó una poda y aplicación de promotores de brotación, para obtener una cosecha adicional en frambuesa roja productora de otoño ‘Malling Autumn Bliss’, crecida en clima templado a 2240 msnm, en un invernadero de polietileno sin calefacción. En enero del 2003 se establecieron los dos sistemas de manejo, el de tres cosechas (SMTC) y el de dos cosechas (SMDC) anuales, sobre plantas de un año de edad previamente trasplantadas a un sustrato compuesto de suelo y arena de tezontle (3:1, v/v). La evaluación se hizo durante 2003 y 2004, con base en la cinética de maduración de frutos, número de cosechas por año, rendimiento y calidad de fruto. En 2004, año en que no hubo heladas tempranas, se obtuvieron tres cosechas de fruto (primavera, verano y otoño) con el SMTC, y dos cosechas (verano y otoño) con el SMDC. Es decir, se logró obtener una cosecha adicional en otoño en los dos sistemas de manejo; esta tercera cosecha fue de 30 a 36 % inferior en rendimiento a la de verano, pero fue igual en calidad de fruto y ocurrió cuando hubo mejores precios que la de verano. Al considerar épocas de cosecha, rendimiento por cosecha y acumulado, y la calidad de fruto, resultó más recomendable el sistema de dos cosechas, porque requiere menos mano de obra para podas y cosechas manuales.
